Alan Bean, the fourth person to walk on the moon and the last surviving member of the Apollo 12 mission, died Saturday in Houston, according to his family and NASA. He was 86."Alan was the strongest and kindest man I ever knew," his wife, Leslie Bean, said in a statement. "He was the love of my life and I miss him dearly." She added he died "peacefully ... surrounded by those who loved him."The retired astronaut fell ill two weeks ago while traveling in Fort Wayne, Indiana, the statement said.Born on March 15, 1932, in Wheeler, Texas, Bean was a test pilot in the US Navy when NASA selected him and 13 others in October 1963 for training to become the third group of NASA astronauts, according to the family obituary shared by the space agency.His first mission to space was in November 1969 as a member of the Apollo 12 crew, the second to land on the moon, it said. He became the fourth man -- and one of only 12 in history -- to walk on the moon.Bean also commanded the second crewed flight to the first US space station Skylab in July 1973."In total, Bean logged 69 days, 15 hours and 45 minutes in space," the obituary said, "including 31 hours and 31 minutes on the moon's surface."After retiring from the Navy in 1975 and NASA in 1981, respectively, Bean became an artist and focused his energy on painting artistic impressions of the moon landing.According to NASA, Bean based that decision on his nearly two decades of experience as an astronaut "during which he visited places and saw things no artist's eye had ever seen firsthand. He said he hoped to capture those experiences through his art."The-CNN-Wire 1632

Allan Lichtman is a historian who wrote “The Keys to the White House,” which outlines 13 metrics for predicting the outcome of a presidential election.Lichtman’s method has proven to work over the years, as he broke from other prognosticators and predicted a Donald Trump victory in 2016.

According to a new study from Common Sense Media and Boston Consulting Group, 30% of students in the U.S. either don't have internet access or access to a device adequate for distance learning. There are 9 million students across the country that don't have either.As another school year affected by COVID-19 inches closer, there are movements not only to prep kids but also to close the digital divide."It's an absolute national tragedy that we can fix," said James Steyer, the founder and CEO of Common Sense Media. "First of all, there needs to be money immediately appropriated in the next stimulus bill that would cover the cost of devices and connectivity for every student and every family in the United States. That's imminently doable and critical to our educational needs."Steyer says it's "shocking" that so many students lack the resources to e-learn — but the students aren't alone. The study also found that teachers are underpaid and working in under-resourced areas."Between 300,000 and 400,000 teachers in this country — essentially 10% of the teaching force — also have the digital divide and don't have the device and connectivity they need to teach in a distance learning environment," Steyer said. "We have a huge challenge, and we need to meet it now."Steyer is leading the charge for change. In a letter to Congress, he and more than a dozen well-known organizations called on lawmakers to "connect all students."One of the organizations in that group was Khan Academy — a non-profit funded by philanthropic donations. The online educational site offers free learning for anyone, anywhere — no strings attached."We've been talking about it well before COVID-19 — that learning should not be bound by time or space," founder Sal Khan said. "Wherever a student is, they should have support to fill in the gaps — to be able to practice things, to get immediate feedback on things, to get lessons on things — wherever they are."There's always a "summer slide" for students — a time when students regress as they fall out of pattern and often spend a portion of the new school year reviewing content. But the slide is deeper this year, thanks to the pandemic."Some of the research partners we work with think there may be a year of loss learning," Khan said. "Not only are kids not learning for those few months, but they're also atrophying — forgetting. And they're going to be out of school for so long; they'll have lost the habits of school."Khan said entire school districts and states aren't doing the educational prep they should be doing. Districts everywhere are scrambling to figure out what school will look like this fall and what their curriculum should entail."If we don't do a full-court press here, some very bad things could happen," Khan said.Right now, Khan Academy is working with school districts to prepare. They estimate a huge increase in users this fall."It's great, we're reaching 30 to 40 million. But, how do we reach them deeply, and how do we move the dial for them?" Khan said. "There's a billion kids we need to reach and reach deeply."Steyer says the way to reach those kids is through Congressional funding."We have been in touch with leaders on both sides of the aisle in House and Senate," Steyer said. "We almost had funding for the digital divide in the first major stimulus package, but it got taken out at the last minute. But we are optimistic that people will do the right thing once and for all and put the resources into the next stimulus package that will make it possible for all kids to do quality distance learning in this country."Steyer says the time is now for supporters to join their charge, or call local leaders so that they can, in some way, affect the learning loss and close the digital divide. 3778

Across the country, as coronavirus testing has increased, so have the long lines waiting to take a test. Some people are reporting having to wait nearly two weeks for results, in some cases.Arizona State University's Biodesign Institute says their new saliva test could be a real game-changer in getting a better handle on this pandemic.On July 10, ABC15 met Heidy Gonzales who was in line for free testing through the HeroZona Foundation at South Mountain Community College."There are some people who have been coming twice, three times," she explained.That was the story for another young woman we met, Mika, who says she had been to the same testing site the day before and was turned away. After extended family tested positive, she didn't want to take any chances. She says, she didn't have a choice but to come back. And it's not just long lines but also long wait times, with some people waiting as long as two weeks to get results. But ASU's new saliva test could be a possible solution to speeding up the process."The accuracy is as good as the nasal swab, if not better," explains Dr. Joshua LaBaer, director of ASU's Biodesign Institute.Dr. LaBaer says these spit samples are not only quicker to collect, but results come back in 24 to 48 hours.So far, ASU has hosted several testing events across the Valley with more planned in the coming weeks.For more information, go to Biodesign.asu.edu.This story originally reported by Nick Ciletti on abc15.com. 1473
